How to Prevent Reinforcement Corrosion on Site?
Corrosion of steel bars is highly detrimental for reinforced concrete elements and might undermine their serviceability and even cause structural failure. However, various precautions can be taken to prevent corrosion of steel bars on construction sites. Concrete with high quality ...
Exposure Conditions Affecting the Durability of Concrete
Different exposure conditions are established based on the degree of severity of the environmental conditions of the area in which the structure is located. Various codes such as Indian Standard, American Concrete Institute, and European Standard have set similar exposure ...
Can Carrots Make Concrete Greener and Stronger?
Celluloses from carrots are being studied as part of a research to contribute to a much stronger and environmentally friendly concrete. A group of researchers at Britain’s Lancaster University used nanoparticles from root vegetables like carrots to produce stronger concrete. ...

Concrete sealing compounds or concrete sealers are liquids applied on the hardened concrete surface to prevent the penetration of deicing solutions, carbon-di-oxide, acids, water, etc. into the concrete. The penetration of such materials results in corrosion of reinforcing steel and ...
Design of Concrete Structures for Durability
Adequate concrete durability can be obtained in the design phase when a structure is conceived, and structural calculations are made, details are designed, materials and their proportions, as well as possible additional preventative measures, are selected. Prevention is further materialized ...
Concrete Durability Requirements Based on ACI-318-19
The ACI 318-19 set durability demand for concrete based on the category exposure and class exposure of the structure, dependent on the ground and weather situation of the area. Each exposure category contains different class exposure. The class exposure describes ...
